Villain was a remainder of a table that broke from 6 players and decided to stay and play HU.
I have 200+ hands for 6max on villain, not sure how to filter these out to just list the HU stats. But villain has 3bet 10/38=26% which is pretty high I think?
I have 4bet twice and got shipped on both times instantly and I folded. We have played less than 80 hands HU.
I haven't seen villain pot - 3/4pot instead of half pot a 3bet hand yet, but I've only called like his 3bet like 3 times.

This two hands might be of relevance and are of the earliest hands of the match

OK so I'm not very experienced with NLHU so please explain things with detail if possible.
My questions,
1) Are hands like T9s and A8s OK to flat vs an aggro 3better?
2) What's a normal number for 3b% HU at these stakes?
3) How often and what hands should I be looking to 4bet vs this type of opponent?
4) As played, shove (for like a minraise), flat or fold and why?

I'm leaning towards shove, because he can be barreling with a ton of draws/obv has to call once I minraise. and will post results after some comments.
Much thanks.

ye calling with those hands is good and i probably call quite a bit wider than that, but only if you feel comfortable playing postflop.

amount to 3-bet depends on a few things:
-how often villain is opening (if it is a 6-max table he may not adjust enough and not raise enough or may over-adjust)
-how villain reacts to 3-bets. if they are never folding, just 3-bet for value, but widen you value range. if they are folding a lot, keep 3-betting a wide range of hands on the edge of your calling range and maybe flat a few stronger hands, ie. KQ,KJ.
- how villain is playing postflop. i they are playing really weak, you can just 3-bet a ton and c-bet.
i'd say around 20% is a good amount too 3-bet.

if they are 3-betting a lot you can just start 4-bet jamming more smaller pocket pairs. tbh i don't think 4-bet bluffing is hugely important at small-stakes and isn't something that should be done really often. if they are 3-betting a lot and playing well post-flop, don't play them find someone else.

ye i'd probably just shove for the reasons that you stated. he can have a lot of over-cards/draws and are quite a lot of bad river cards for us. also he can have worse 8's/pair+draw hands that he's not gonna fold.

1st hand, i fold river
2nd hand, i stab at flop for sure and/or turn
3rd hand, i'm stacking off i think, just ship the rest in on the turn

1) yep those hands are ok vs aggro 3better
2) at nl10 i have no clue, but in general 15%-20% is pretty std
3) vs his 26% 3bet, i'd be 4betting 88+ AJ+, and a few rand bluffs like A2o, K3s, 68o, etc
4) just ship the rest, no point call/call'ing with stack to pot ratio being so low

hand 1: what range do you put villain on on river? random 2 pairs? I was thinking that he wasn't good enough to bet a T that big, and definitely wasn't betting a smaller pair. so that's why I called
hand 2: i'm probably clueless here - when he 3bets and checks, doesn't that mean he's either got a made hand or good showdown value with A high? meaning he'll call me down?

hand 1 - i fold flop always, even if A-high is good there's a ton of cards that will make you have to fold OTT/R

hand 2- betting flop and turn here get him to fold his mostly mostly A-high range - why would he ever check an overpair on this board, i think he bets alot of his K4,5 type hands here aswell on a board this scary - easy fold if he raises

hand 3 - shuv turn - i will probably raise the flop mostly get it in vs alot of draws, some 2nd pair hands and occasionally AK/AQ ship

Well, he doesn't barrel the Qh which is a pretty nutted barreling card, so I just don't expect him to have that much air, surely he'd have fired most bluffs on this turn. He sure reps Tx well (although admittedly good Tx should be firing turn, I think alot of people check at these stakes), and pretty sure the vast majority of people bet like any Tx here, and it's not a particularly large bet. Calling isn't terrible if you never expect him to to value bet thin, but then again any Tx isn't thin, and people who don't vbet well are often the sort of people who will randomly check back a turned Q, so in general I just give them credit for a better hand and muck river. Fwiw I think flop c/c is fine.

Hand 2 is a board that hits your range better than his. It's awful for his big broadway combos, and overpairs are nearly always firing because of the scary texture. You should be stabbing here pretty regularly, because it's such a common spot for villain to just check/fold.
